China DMC Series Pulse Bag Dust Collector - High Efficiency Dust Control from Leading Suppliers & Factory
Working Principle
Dust-laden air enters the next ash bucket by fan powered via the inlet, then speed dips, large weight dust particles fall into the ash bucket, fine dust into the cabinet with the airflow, and out of the discharge outlet after the purification treatment by the sieve of the filter bag. The dust which separated outer of the surface of the filter bag makes the resistance increases gradually, this time the controller send up signal according to the set resistance range, electromagnetic pulse valve is open, the high-pressure air which in the air bag spray quickly, through the Venturi tube several times in the first wind-induced ambient air into the filter bag, so the filter bag instant expansion, and the dust is shaken off and falling into the dust hopper.
Characteristic and feature of DMC series pulse bag dust collector
- (1) There is no need for pre-dust removal equipment, which can deal with the dust of up to 1000mg/m3 at one time, and the emission is less than 50mg/m3, and the process is simple;
- (2) There is no need to spray pipe in the bag room, and it is convenient to change the bag outside the machine;
- (3) Embedded elastic bag mouth, good sealing performance;
- (4) The number of pulse valves is small, the cleaning strength is large, and the action is rapid;
- (5) The machine adopts microcomputer automatic control, each parameter is easy to adjust, can achieve no post work;
- (6) filter bag service life of more than two years;
- (7) Easy to achieve isolation maintenance.

Frequently Asked Questions (FAQ)
How does the DMC series pulse bag dust collector work?
Dust-laden air enters the ash bucket via the inlet, where the speed dips, causing large weight dust particles to fall. Fine dust travels with the airflow into the cabinet, where it is purified by the filter bag and discharged. When the resistance builds up to a set range, the controller opens the electromagnetic pulse valve to release high-pressure air, instantly expanding the filter bag and shaking the dust off into the hopper.
What is the dust concentration limit and emission level for this equipment?
The DMC series pulse bag dust collector can handle dust concentrations of up to 1000mg/m³ at one time, keeping the final emission below 50mg/m³.
How long is the service life of the filter bag?
The filter bags in the DMC series pulse bag dust collector have a service life of more than two years.
Does the system require manual control for cleaning operations?
No, the machine adopts microcomputer automatic control. Each parameter is easily adjustable, allowing for unattended (no post) work.
Is maintenance easy for the DMC series pulse bag dust collector?
Yes, it features an embedded elastic bag mouth with good sealing performance, convenience for changing bags outside the machine, and easily achievable isolation maintenance.
